Learn How to Win Material: Pin Tactic
This middlegame puzzle shows how a pin can turn into a decisive tactical gain. One piece is tied to the king, which means it cannot move freely without exposing a more valuable target. When that restriction is combined with a forcing check, the defender is often overloaded and the position can collapse quickly. The key idea is to look for a move that creates immediate threats while also exploiting the pinned piece and the exposed king.
